Dmitry, please check it out.
Looks like a chicken-and-egg problem to me.

Description:
------------
segfault caused by setting properties to null in __destruct()
Reproduce code:
---------------
<?php
class Person {
public $dad;
public function __destruct() {
$this->dad = null; /* no segfault if this is commented out */
}
}
class Dad extends Person {
public $son;
public function __construct() {
$this->son = new Person;
$this->son->dad = $this; /* no segfault if this is commented
out */
}
public function __destruct() {
$this->son = null;
parent::__destruct(); /* segfault here */
}
}
$o = new Dad;
unset($o);
?>
Expected result:
----------------
No segfault
Actual result:
--------------
PHP crashes due to a segfault (crashes apache worker thread when
running as apache module)
